* Continued looking at big-endian/quad-vector patch: attempted to figure out the proper semantics for vec_extract in big endian mode (about 1 day). Put on hold temporarily to work on lp675347, QT failing to build due to constraint failure in inline asm statements used for atomic operations: found the patch which introduced the failure, and suggested a workaround to the OP. Came up with a plausible-looking patch, and started testing it, after spending some time trying to figure out why ARM Linux mainline doesn't build at present. Patch sent upstream.
